Lacking and Slacking

Here is an interesting BBC article explaining the international despair over Darfur. The most telling, paragraph, comes near the end:

Darfur has found itself a crisis that neither the UN nor the relatively new African Union can solve. The UN has lacked the will to intervene and the African Union has lacked the means.

How is it that we go into Iraq, but not Sudan? If preemption could possibly apply to a crisis like this, then sign me up for that ideology. We need to quit sitting on our hands. We need to quit letting a few pain-in-the-a Sudanese power-hungry leaders keep millions of people in unthinkably horrible circumstances.
